2011.02.14 WL, Ha & CaK 太阳

[universe24]

WL: 白光太阳...Baader Solar Film + Marumi Green filter + Hoya ND4 + 1.6x extender + SBIG-4020M
Ha: 38mm ERF + Daystar 0.45A Ha + SBIG-4020M
CaK: Lunt CaK solar telescope + Lumenera SKY-nyx 2-1M

由于电脑只有一台，三个频道的太阳并不是同时拍摄，先拍摄白光，然后是CaK，左后是Ha。

The sun suddenly has lots of interesting regions today after many days of relative quietness, but shame about the weather over here or I would get my gears out for the interesting activities today. For someone who has not experienced solar maximum with solar equipment (i.e. me!), the activities today are really fantastic.

I really love the CaK image. The animation is very nice. I like the smooth transtion from one shot to another.

[Boogie]

我回去問問主人，想不想統整一下文章，講講太陽是如何觀測的?　

[willis]

Too bad! The weather in HK will not be good anyway! I wish there is a gap in the sky so that I can have a quick look!

[willis]

According to http://www.solarmonitor.org/ , the activity is high today.

終于又再看到william的太陽攝影了~~
很期待考完試回去家裏把望遠鏡拿出來曬曬太陽，順便看黑子~

Wow, an X-class solar flare erupted on 15-2-2011!

David，其实我也是观测太阳的新手，来着的太阳活跃期，有排忙了...。
迟些或许会进多两台电脑分别操控不同的频道，但还是面对着harddisk储存量不够，由于使用SKY-nyx 2-1M，10fps拍摄，以这样活跃的黑子区，至少每隔一分钟就要拍摄一段30秒，1GB的影像，要每天准备500MB才可以应付了。

如果此黑子区持续活跃到太阳的边缘，到时可以尝试以CaK拍摄出磁场的线条出来。

记得要用太阳滤光纸啊。

一定會記得的~我不想我的眼睛瞬間蒸發~~

Dear universe,
What is the aperature of the CaK telescope?
Regards,
Willis

[universe24]

Dear willis,
The CaK telescope is 60mm only.
If I wanna zoom just sunspot to be capture, I will take out the CaK module and place it on larger aperture.
Anyway, the CaK module is just can use on aperture below 100mm.

[社長]

Anyway, the CaK module is just can use on aperture below 100mm.

design an ERF and pass only Cak spectrum line for your 152APO

[universe24]

Perhaps Lunt can do so? Just don't how is the cost for custom make one...

[社長]

no, I never heard that. Though I am sure Lunt can make one, but will be expensive.

觀察太陽真的令自己整日都很忙碌，日間拍攝了數gigabytes的片段後，總要數小時處理，同日晚上卻又可能好天，外出觀星，第二天又可能繼續晴天，又要拍攝，但昨日的片段仍未處理……

有些時候，當日間晴天時，我竟會希望晚上有雲呢。

[universe24]

最近这几晚我这儿的天气都不错，虽然不是整晚都晴天...但太阳上面的活动似乎比较刺激，日日新鲜日日坚，所以晚上暂时割舍了。
前两天拍摄的一些Ha放大摄影，到现在还没处理完毕，整26条1GB的资料。

期待中!

Very Good picture.
But it seems that the activities of sun is very active........
